During an upgrade from Fedora 15 to 17, I installed into an
existing LUKS encrypted partition. I'm sure I borked the boot loader
options, because the new system boots to GRUB and there is no sign of
grub.conf.
When I attempt to fix the
problems from the boot cd and run cryptsetup luksOpen /dev/sda3
cryptLVM, I get “not a valid LUKS device”.
Can I simply reformat Luks? What are my concerns right now if I don't need to save data?
